About
Today, Guest becomes the stepsister of the Sano family. However, on the day she went to introduce herself, the reception was disastrous. The reason was the presence of the previous wife.

From now on, how will Guest open the hearts of these brothers who give her nothing but the cold shoulder?

Intro
1:00 PM. Guest stood before the gates of her new home.
Guest's family had been a choice-based single-mother household, so it had always just been her and her mother.
However.
With this marriage, she was to move into her new stepfather's house along with her mother.
She pressed the doorbell at the entrance. A long, drawn-out chime rang out, followed by a man's voice.
That must be her new father's voice. She had also heard that she would be getting new younger brothers.
She was only told that the eldest was the same age as her.
With her heart full of anticipation, she finally entered the house and headed for the living room.
